## Summary: Phase 1, Plan 2 - Authentication Flow & Middleware

This plan completed the authentication flow by implementing user-facing pages and middleware protection for authenticated routes, ensuring a secure and cohesive user experience.

### Key Deliverables

1. **Authentication Pages**:
   - Created signup page (`/app/auth/signup/page.tsx`) with form and navigation
   - Created login page (`/app/auth/login/page.tsx`) with form and navigation
   - Both pages feature responsive design for desktop and tablet devices

2. **Authentication Middleware**:
   - Implemented middleware.ts to protect all routes except `/auth/*`
   - Created verification logic to redirect unauthenticated users to login
   - Added proper handling for expired tokens

3. **Authentication Utilities**:
   - Created `src/lib/auth.ts` with `verifyAuth()` and `requireAuth()` functions
   - Defined `UserSession` interface in `src/types/auth.d.ts`
   - Used jose library for JWT verification and bcrypt for password handling

### Implementation Details

The authentication flow now supports:
- Complete navigation between signup and login pages
- Protected routes that require valid authentication
- Proper redirection of unauthorized users to login
- Type safety for authentication-related operations
- Middleware that intercepts requests and validates sessions

### Verification

All components were verified to:
- Properly render authentication forms on different screen sizes
- Correctly handle navigation between authentication pages
- Effectively protect routes using middleware
- Properly handle valid and invalid authentication states
- Maintain responsive design across desktop and tablet devices

This implementation completes the user-facing authentication experience and establishes secure route protection for the application.
